The South London Liberal Synagogue is a Liberal Jewish congregation and synagogue, located at 1 Prentis Road in Streatham in the Borough of Lambeth, London, England, in the United Kingdom.

Its first president was Lily Montagu, one of Liberal Judaism's founders.

From 1929 until c. 1935, the congregation worshiped from Tudor Hall, on Pinfold Road, Streatham; and subsequently from Farnan Hall, on Hopton Road.

The congregation moved to its present home in Prentis Road (formerly a girls’ school) in 1938.
